The diastereoselective formation of 2,3,4-substituted piperidines is achieved by condensation of the iron dienal complex 2 and the primary amine 3via an intramolecular Mannich-type cyclisation. This method is illustrated by the first total synthesis of (±)-dienomycin C 1 and its C-4 epimer 9.
2,3,4-取代的哌啶的非对映选择性形成是通过分子内曼尼希型环化反应使铁二烯络合物2和伯胺3缩合而实现的。该方法通过(±)-地诺霉素C 1及其C-4差向异构体9的首次全合成来说明。
